Guidelines on small bowel enteroscopy and capsule endoscopy in adults.R Sidhu, D S Sanders, A J Morris, and M E McAlindon Gut 2008;57 125-136
The small bowel has historically been a difficult area to examine due to its anatomy, location and relative tortuosity. Examination beyond the duodenojejunal flexure is of importance in a number of small bowel disorders. Before the advent of enteroscopy or capsule endoscopy, radiographic studies had been the main investigative modality of the small bowel. Barium follow-through and enteroclysis permits indirect examination of the small bowel but has a low diagnostic yield particularly in the context of obscure gastrointestinal bleeding.
